Lexington, KentuckyAges 18 years+ - NCT05528133RecruitingPhase 2
Personalized radiation based on tumor genetics in triple-negative breast cancer
This trial tests whether using tumor “genetics” (information from your biopsy) to guide radiation planning can improve treatment for triple-negative breast cancer. It may help by aiming radiation more precisely while still using standard approaches where needed.
Clearwater, FloridaAges 18 years+ - NCT05534438RecruitingPhase 2
Tested targeted radiation plus usual drug treatment in metastatic breast cancer
This Phase 2 study tests whether adding a very focused type of radiation to standard drug treatment can better control metastatic breast cancer. It is for people whose cancer is only progressing in one spot, seen on a PET scan.
Basking Ridge, New JerseyAges 18 years+ - NCT05491512RecruitingPhase 2
Reduced radiation with chemo for HPV throat cancer
This trial tests whether giving less radiation (while using standard chemotherapy) can treat HPV-related throat cancer effectively. It may help reduce radiation exposure while still controlling the cancer.
Basking Ridge, New JerseyAges 18 years+ - NCT05491226RecruitingPhase 2
Pembrolizumab plus radiation and myeloid-targeting for high-risk breast cancer
This trial studies whether adding pembrolizumab (an immune “unlocking” drug) to radiation and another treatment that targets certain immune cells can improve outcomes for women with high-risk, early-stage triple negative breast cancer. You may be considered if your cancer has signs that it may respond less to immunotherapy on its own.
Los Angeles, CaliforniaAges 18 years+ - NCT05419518RecruitingPhase 2
Higher-dose radiation to ease pain from metastatic tumors
This Phase 2 study tests whether a stronger (higher-dose) radiation plan can better reduce pain from tumors that have spread to bone or other areas. It’s meant to help people live more comfortably by targeting painful spots while avoiding certain high-risk situations.
Hamilton, New JerseyAges 18 years+ - NCT05423210RecruitingEarly Phase 1
Atezolizumab with pre-surgery brain radiation for glioblastoma
This early-phase study tests atezolizumab (an immune therapy) together with radiation before brain surgery for glioblastoma. It aims to make the treatment safer and more effective before the tumor is removed.
Stony Brook, New YorkAges 18 years+ - NCT05412082RecruitingPhase 1
Smart chemo and radiation plan for locally advanced rectal cancer
This Phase 1 study tests a “smart” total treatment plan using chemotherapy (chemo) and radiation before surgery for people with locally advanced rectal cancer. The goal is to see if this approach is safe and can work well while helping plan treatment based on your situation.
Miami, FloridaAges 18 years+ - NCT05406232Recruiting
Radiation study to track immune changes in breast cancer
This study gives a short course of radiation to the breast or chest wall and measures how your immune system responds. It may help doctors better understand which immune changes happen after radiation and how this could improve palliative (symptom-relieving) care.
Houston, TexasAges 18 years+ - NCT05361798RecruitingPhase 2
Testing immune response after prostate radiation with or without a drug
This study checks how your immune system’s cancer-fighting cells change after stereotactic body radiation (SBRT) to the prostate. It compares SBRT alone versus SBRT plus an immunotherapy drug (PDS01ADC) in men with intermediate- or high-risk localized prostate cancer treated with hormone therapy (ADT).
Bethesda, MarylandAges 18 years+ - NCT05354570RecruitingPhase 2
Radiation for thymic cancer that has spread to lung lining
This Phase 2 study tests a precise type of chest radiation that targets cancer in the lung lining (pleura) while trying to protect healthy lungs and organs. It may help people with thymic cancer that has spread to the pleura, including cases that return after prior treatment.
Basking Ridge, New JerseyAges 18–79 - NCT05351424Recruiting
Spanish-language cancer care support for breast or prostate radiation
This study tests an educational and communication support program to help Spanish-speaking people stay on track with treatment when they’re getting radiation for non-spread (non-metastatic) breast or prostate cancer. It may help by improving understanding through interpreter-supported visits.
Miami Beach, FloridaAges 18 years+ - NCT05317026Recruiting
Test adding cement injection to SBRT for spine pain
This study tests whether adding a vertebroplasty procedure (a cement injection to stabilize a spine bone) to standard SBRT radiation can reduce pain from spinal metastases. It may help people with painful, possibly unstable spine lesions by improving early pain relief.
Montreal, QuebecAges 18 years+ - NCT04587739RecruitingPhase 1
Radiation before surgery for a single liver tumor
This early feasibility study tests a radiation plan given before surgery for hepatocellular carcinoma (a type of liver cancer) to see if it’s safe and doable. It may help shrink or control the tumor before an operation that aims to fully remove it.
LilleAges 18–70 - NCT05223803RecruitingPhase 2
Study radiation for early metastatic prostate cancer
This Phase 2 trial tests a radiation-focused approach for people with newly diagnosed (de novo) prostate cancer that has spread to a small number of spots, especially in bone. It aims to see how well the treatment controls the cancer while keeping side effects manageable.
La Jolla, CaliforniaAges 18 years+ - NCT05172245RecruitingPhase 1
Testing a new drug added to chemoradiation for head and neck cancer
This study tests whether adding a new targeted drug called ipatasertib to standard chemoradiation can improve treatment for people with locally advanced head and neck cancer. Ipatasertib may help block a protein that helps cancer grow, possibly making the standard therapy more effective.
Tampa, FloridaAges 18 years+ - NCT05124912Recruiting
Laser treatment for recurrent brain metastases after prior SRS
This study tests whether repeating treatment with a laser (along with a small biopsy) can control brain metastases that have come back after earlier radiation called SRS. It may help people whose cancer is stable enough for surgery and who have a specific, reachable brain spot to target.
Los Angeles, CaliforniaAges 18 years+ - NCT05136846RecruitingPhase 1
Papaverine with chemoradiation for stage II–III lung cancer
This early-phase trial tests whether adding papaverine to standard chemoradiation can improve treatment for stage II–III non-small cell lung cancer (and some limited stage IV cases). It aims to see if the combination is safe and tolerable while targeting the cancer with radiation and chemotherapy.
Duarte, CaliforniaAges 18 years+ - NCT05083754RecruitingPhase 1
New glioblastoma trial testing immune drug plus radiation
This Phase 1 study tests whether adding an immune therapy called retifanlimab to radiation (and a chemotherapy medicine called temozolomide, in some parts of the study) is safe and helpful for newly diagnosed glioblastoma patients after surgery with carmustine wafers. It aims to see how well this combination controls the cancer and what side effects are expected.
Baltimore, MarylandAges 18–100 - NCT05100095RecruitingPhase 2
Radiation schedule study for Merkel cell skin cancer
This Phase 2 trial tests a specific radiation timing/dose schedule for Merkel cell carcinoma (MCC), a rare and aggressive skin cancer. It may help by improving control of the cancer after surgery, especially in higher-risk cases (like lymph nodes).
Houston, TexasAges 18 years+ - NCT05079763Recruiting
Hydrogel treatment to reduce skin damage after breast radiation
This trial tests a bacterial cellulose–based gel with a soothing ingredient (monolaurin) to help prevent or lessen painful skin reactions in the area receiving breast radiation. It focuses on people who have already finished surgery and chemotherapy and are about to start a planned radiation treatment schedule.
ManilaAges 18–80 - NCT05068232RecruitingPhase 2
Durvalumab plus targeted radiation for metastatic small cell lung cancer
This Phase 2 study tests durvalumab (an immunotherapy) together with focused, ablative radiation to treat metastatic small cell lung cancer. It may help shrink tumors and improve outcomes, especially when at least one tumor can be safely targeted with this radiation plan.
Chicago, IllinoisAges 18 years+ - NCT05047094Recruiting
DaRT radiation plus pembrolizumab for head and neck cancer
This trial tests whether a targeted internal radiation treatment (DaRT) combined with pembrolizumab (an immune therapy) can shrink recurrent or metastatic head and neck squamous cell cancer that cannot be fully removed with surgery. It may help by making cancer more visible to the immune system while delivering localized radiation to a tumor area.
JerusalemAges 18 years+ - NCT05039632RecruitingPhase 1/Phase 2
NBTXR3 plus radiation with anti-PD-1 for advanced lung or liver cancers
This study tests whether adding NBTXR3 (given into a tumor) and targeted radiation to anti–PD-1/PD-L1 immunotherapy can improve cancer control in advanced cancers that have spread to the lung and/or liver. Participants may be assigned to different radiation approaches to try to trigger tumor shrinkage in both treated and nearby or distant tumor areas.
